Maybe on Sub 2  they can do something similar or at least have a disclosure document like we see in all the 50 disclosure docs RE agents have to use to sell houses. ??? 

My biggest challenge was finding an effective property manager as I was not able to manage it myself.

I've contacted property management companies as well and have scheduled meetings with them as well.

While I don't own a brokerage, I have been managing a team of RE agents for over 5 years. 

Read BP books (The Book on Rental Property Investing, Managing Rental Properties, Set For Life), watch Youtube videos, etc. 

There are some good property managers over there and contractor rates are cheaper than the western part of the state. 

Having some clue about property management and tenant relation will definingly help your success in this field.

Do property management companies need a real estate license? 

I disagree,  if you know how to manage your other debts best to buy sooner and get the asset

Your $600 should be over $1200 a month if you split up that $500K over (2) properties (Outside of California) you could double up on your NOI.The age old question is out of state management - my reply is if its turn key or renovated it will need very little management other than lawn and once in a blue moon repair.
